Port configuration migration system

ABSTRACT

A port configuration migration system includes a primary I/O module connected to a server device via a secondary I/O module. A fabric manager system maps a virtual interface to a first downlink port on the primary I/O module that is connected to the secondary I/O module, with the virtual interface providing a virtual direct connection to the server device. The fabric manager system then configures the virtual interface with communication configuration information for the server device such that communications received via the first downlink port are transmitted using the virtual interface. The fabric manager system then receives a discovery communication from the server device via a second downlink port on the primary I/O module that is connected to the secondary I/O module, and remaps the virtual interface to the second downlink port such that communications received via the second downlink port are transmitted using the virtual interface.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present disclosure is a continuation of U.S. patent application Ser. No. 16/946,907, filed on Jul. 10, 2020, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND

The present disclosure relates generally to information handling systems, and more particularly to migrating port configuration information for ports on information handling systems.

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

Information handling systems such as, for example, server devices, may be connected to each other and/or a network via Input/Output (I/O) modules in order to transmit communications between each other and/or via the network. For example, primary I/O modules may be connected via secondary I/O modules to server devices, and may be connected to each other and/or a network via switch devices (e.g., leaf and spine switch devices) as well. As will be appreciated by one of skill in the art in possession of the present disclosure, the physical I/O module configuration discussed above may allow a first server device connected via a first secondary I/O module to a first primary I/O module to communicate through the Internet via an Internet device connected to a switch device, or with a second server device connected via a second secondary I/O module to a second primary I/O module via a switch device(s). However, the primary I/O module/secondary I/O module configurations discussed above can raise some issues.

For example, the secondary I/O modules may be connected via their secondary I/O module uplink ports to primary I/O module downlink ports on the primary I/O modules, and the primary I/O modules may be provided server device communication information that allows the primary I/O modules to transmit server device communications received via those secondary I/O modules from any server device. However, in conventional systems, the configuration information to allow the transmission of server device communications received from any particular server device is “tied” to the secondary I/O module connected to that server device such that, when the connections from that secondary I/O module to a primary I/O module changes (e.g., cabling from that secondary I/O module is connected to different primary I/O module downlink ports), the primary I/O module to which the secondary I/O module was connected must be reconfigured in order to be able to transmit communications received from the server devices via the new connections, requiring a user or other network administrator to reconfigure the primary I/O module and resulting in system downtime.

Accordingly, it would be desirable to provide a port configuration system that addresses the issues discussed above.

SUMMARY

According to one embodiment, an Information Handling System (IHS) includes a processing system; and a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a fabric management engine that is configured to: map a virtual interface to a first primary I/O module downlink port on a primary I/O module that is connected to a first secondary I/O module uplink port on a secondary I/O module, wherein the virtual interface provides a virtual direct connection of the virtual interface to a server device that is connected to the secondary I/O module; configure the virtual interface with server device communication configuration information for the server device such that data communications received via the first primary I/O module downlink port are transmitted using the virtual interface configured with the server device communication configuration information for the server device; receive, via a second primary I/O module downlink port on the primary I/O module that is connected to a second secondary I/O module uplink port on the secondary I/O module, a discovery communication from the server device; and remap, based on the receiving of the discovery communication via the second primary I/O module downlink port on the secondary I/O module from the server device, the virtual interface to the second primary I/O module downlink port such that data communications received via the second primary I/O module downlink port are transmitted using the virtual interface configured with the server device communication configuration information for the server device.

Referring now to FIG. 2 , an embodiment of a port configuration migration system 200 is illustrated. In the illustrated embodiment, the port configuration migration system 200 includes a fabric 202 having a plurality of primary Input/Output (I/O) modules 204 a and 204 b. However, while only two primary I/O modules are illustrated and discussed below, one of skill in the art in possession of the present disclosure will appreciate that that port configuration migration system 200 may include more or fewer primary I/O modules while remaining within the scope of the present disclosure as well. In an embodiment, either or both of the primary I/O modules 204 a and 204 b may be provided by the IHS 100 discussed above with reference to FIG. 1 , and/or may include some or all of the components of the IHS 100. In a specific example, either or both of the primary I/O modules 204 a and 204 b may be provided by a DELL® EMC® networking MX9116n fabric switching engine switch device, available from DELL® Inc. of Round Rock, Tex., United States. One of skill in the art in possession of the present disclosure will appreciate that the primary I/O modules 204 a and 204 b may be provided by “full-function” I/O modules that include an operating system and that may be configured to perform any of a variety of I/O module functions known in the art in handling server device communications, discussed in further detail below, and in specific examples may include networking hardware providing networking functions capable of supporting the secondary I/O modules discussed below that are coupled to them via double-density connections. However, while illustrated and discussed as being provided by particular type/functionality I/O modules, one of skill in the art in possession of the present disclosure will recognize that the port configuration migration system 200 may include any devices that may be configured to operate similarly as the primary I/O modules 204 a and 204 b discussed below.

In the illustrated embodiment, the fabric 202 in the port configuration migration system 200 also includes one or more secondary I/O modules 206 a coupled to the primary I/O module 204 a, and one or more secondary I/O modules 206 b coupled to the primary I/O module 204 b. For example, each secondary I/O module may be coupled to one of the primary I/O modules 204 a and 204 b via an aggregated link (e.g., a VLT port channel in the VLT protocol), and one of skill in the art in possession of the present disclosure will appreciate that each primary I/O module 204 a and 204 b may typically be coupled to between 1-9 secondary I/O modules, while being capable of coupling to up to 12 secondary I/O modules. In an embodiment, any or all of the secondary I/O modules 206 a-206 b may be provided by the IHS 100 discussed above with reference to FIG. 1 , and/or may include some or all of the components of the IHS 100. In a specific example, any or all of the secondary I/O modules 206 a-206 b may be provided by a DELL® MX7108 expander module, available from DELL® Inc. of Round Rock, Tex., United States.

One of skill in the art in possession of the present disclosure will appreciate that the secondary I/O modules 206 a-206 b may be provided to enable their connected primary I/O module to couple to additional server devices (discussed in further detail below) and, as such, may not include an operating system, and may not be configured to perform many (or all of) the variety of I/O module functions performed by the primary I/O modules 204 a and 204 b, discussed in further detail below, and in specific examples may and electrical pass-through device connected via double-density connections to the primary I/O modules discussed above. However, while illustrated and discussed as being provided by particular type/functionality I/O modules, one of skill in the art in possession of the present disclosure will recognize that the port configuration migration system 200 may include any devices that may be configured to operate similarly as the secondary I/O modules 206 a-206 b discussed below.

In the illustrated embodiment, the fabric 202 in the port configuration migration system 200 also includes one or more server devices 208 a coupled to the primary I/O module 204 a, one or more server devices 208 b coupled to one or more of the secondary I/O modules 206 a, one or more server devices 208 c coupled to one or more of the secondary I/O modules 206 b, and one or more server devices 208 d coupled to the primary I/O module 204 b. In an embodiment, any or all of the server devices 208 a-208 d may be provided by the IHS 100 discussed above with reference to FIG. 1 , and/or may include some or all of the components of the IHS 100.

Furthermore, each primary I/O module rack chassis that houses a pair of primary I/O modules may also house server devices that are directly connected to those primary I/O modules (e.g., the server devices 208 a and 208 d directly connected to the primary I/O modules 204 a and 204 b, respectively. However, one of skill in the art in possession of the present disclosure will recognize that each primary I/O module rack chassis may be limited to housing a maximum number of server devices (e.g., 8 server devices in many conventional rack chassis), while each of the primary I/O modules may be configured to handle communications from many more server devices.

Furthermore, each secondary I/O module may be provided in a respective rack chassis (e.g., a “secondary I/O module rack chassis”) with the server devices 208 b-208 c (e.g., 8 server devices in each rack chassis) that are connected to that secondary I/O module, and each secondary I/O module is connected to one of the primary I/O modules (which is housed in primary I/O module rack chassis) in order to couple the server devices in its secondary I/O module rack chassis to a primary I/O module. As discussed above, the primary I/O module may be a “full-function” I/O module that includes an operating system and that may be configured to perform a variety of I/O module functions for any server device (e.g., that is directly connected to that primary I/O module, or that is coupled to that primary I/O module by a secondary I/O module), while the secondary I/O modules do not include an operating system and are not configured to perform many (or all) of the variety of I/O module functions, as the purpose of the secondary I/O modules is to simply connect primary I/O modules to additional server devices that are not located in its primary I/O module rack chassis.

For example, the chassis 602 may house a processing system (not illustrated, but which may include the processor 102 discussed above with reference to FIG. 1 ) and a memory system (not illustrated, but which may include the memory 114 discussed above with reference to FIG. 1 ) that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a fabric manager engine 604 that is configured to perform the functionality of the fabric manager engines and/or fabric manager systems discussed below. As discussed above, in some examples, the functionality of the fabric manager engine 604 may be provided by the primary I/O module engine 304 in a primary I/O modules 204 a/300 or 204 b/300 while remaining within the scope of the present disclosure as well.

The chassis 602 may also house a storage device (not illustrated, but which may include the storage device 108 discussed above with reference to FIG. 1 ) that is coupled to the fabric manager engine 604 (e.g., via a coupling between the storage device and the processing system) and that provides a fabric manager database 606 that may store any of the information utilized by the fabric manager engine 604 discussed below. The chassis 602 may also house a communication system 608 that is coupled to the fabric manager engine 604 (e.g., via a coupling between the communication system 608 and the processing system) and that may be provided by a Network Interface Controller (NIC), wireless communication systems (e.g., BLUETOOTH®, Near Field Communication (NFC) components, WiFi components, etc.), and/or any other communication components that would be apparent to one of skill in the art in possession of the present disclosure. However, while a specific fabric manager system 600 has been illustrated, one of skill in the art in possession of the present disclosure will recognize that fabric manager systems (or other devices operating according to the teachings of the present disclosure in a manner similar to that described below for the fabric manager system) may include a variety of components and/or component configurations for providing conventional fabric manager functionality, as well as the functionality discussed below, while remaining within the scope of the present disclosure as well.

Referring now to FIG. 7 , an embodiment of a method 700 for migrating port configurations is illustrated. As discussed below, the systems and methods of the present disclosure provide for the automatic migration of port configurations when connections between a secondary I/O module and a primary I/O module change. For example, a secondary I/O module may include a secondary I/O module downlink port that is connected to a server device, as well as first and second secondary I/O module uplink ports that are connected to respective first and second primary I/O module downlink ports on a primary I/O module. A fabric manager system that is coupled to the primary I/O module may operate to map a virtual interface to the first primary I/O module downlink port on the primary I/O module, with the virtual interface providing a virtual direct connection of the virtual interface to the server device, and may then configure the virtual interface with server device communication configuration information for the server device such that data communications received via the first primary I/O module downlink port are transmitted using the virtual interface configured with the server device communication configuration information for the server device. When the fabric manager system receives a discovery communication from the server device via the second primary I/O module downlink port on the primary I/O module (e.g., due to a connection change between the secondary I/O module and the primary I/O module), it remaps the virtual interface to the second primary I/O module downlink port such that data communications received via the second primary I/O module downlink port are transmitted using the virtual interface configured with the server device communication configuration information for the server device. As such, the manual reconfiguration of primary I/O modules in response to connection changes between those primary I/O modules and secondary I/O modules is eliminated, thus eliminating the system downtime associated with such reconfigurations.

With reference to FIG. 8A, an example of specific connections of the primary I/O module 204 a, the secondary I/O module 206 a, and the server devices 208 a and 208 b is illustrated for purposes of the discussion provided below. As illustrated, the primary I/O module 204 a may be included in a rack chassis 800 that also houses the server device 208 a, with the server device 208 a directly connected to that primary I/O module 204 a via, for example, a cable connected to each of an uplink port 802 on the server device 208 a and a downlink port 804 on the primary I/O module 204 a. Furthermore, a rack chassis 806 may house the secondary I/O module 206 a and the server device 208 b, with the server device 208 b directly connected to that secondary I/O module 206 a via, for example, a cable connected to each of an uplink port 808 on the server device 208 b and a downlink port 810 on the secondary I/O module 206 a.

As illustrated, the secondary I/O module 206 a may be connected to the primary I/O module 204 a via a coupling 812 between downlink ports 814 a-814 h on the primary I/O module 204 a and uplink ports 816 a-816 h on the secondary I/O module 206 a (e.g., using a “double density” coupling or other high bandwidth coupling known in the art). For example, each link between the downlink ports 814 a-814 h and uplink ports 816 a-816 h (e.g., the link between downlink port 814 a and uplink port 816 a, the link between downlink port 814 b and uplink port 816 b, etc.) may be a 25 G portion of a 200 G link provided by the coupling 812. However, while a specific coupling between the primary I/O module 204 a and secondary I/O module 206 a is illustrated and described, one of skill in the art in possession of the present disclosure will appreciate that other primary/secondary I/O module couplings will fall within the scope of the present disclosure as well.

The method 700 begins at block 702 where a fabric manger system generates a virtual interface. In an embodiment, at block 702 and following the physical configuration of the port configuration migration system 200 (e.g., to provide the physical connections illustrated in FIG. 8A), and the powering on, resetting, and/or other initialization of that port configuration migration system 200, the fabric manager engine 604 in the fabric manager system 210/600 may operate to generate a virtual interface. In one specific example, the fabric manager engine 604 in the fabric manager system 210/600 may operate to perform discovery operations described in U.S. patent application Ser. No. 16/526,624, filed on Jul. 30, 2019, the disclosure of which is incorporated herein by reference. Similarly as discussed in that application, and with reference to FIG. 8A, following the initialization of the port configuration migration system 200, enclosure controllers (not illustrated) in the rack chassis 800 and 806 may provide the server devices 208 a and 208 b a variety of information including, for example, a rack chassis identity of the rack chassis in which that server device is located, a slot identity of the slot in the rack chassis in which that server device is located, an I/O module identity and I/O module type of the I/O module to which that server device is connected, port identities of the port(s) on that server device that are connected to the I/O module, and/or other information that would be apparent to one of skill in the art in possession of the present disclosure.

In response to receiving the information from the enclosure controller discussed above, the server engine 504 in the server device 500 may generate a discovery communication (e.g., a Link Layer Discovery Protocol (LLDP) communication) including any or all of the information received from the enclosure controller in its rack chassis, and may transmit those discovery communications to their connected I/O module. As such, the server device 208 a/500 may transmit a discovery communication via its communication system 508 to the primary I/O module engine 304 in the primary I/O module 204 a/300, with that discovery communication identifying itself, the rack chassis identity of the rack chassis 800 in which the server device 208 a is located, a slot identity of the slot in the rack chassis 800 in which the server device 208 a is located, an I/O module identity and I/O module type of the primary I/O module 204 a to which the server device 208 a is connected, a port identity of the port 802 on the server device 208 a that is connected to the primary I/O module 204 a, and/or other information that would be apparent to one of skill in the art in possession of the present disclosure. As will be appreciated by one of skill in the art in possession of the present disclosure, the port configuration migration functionality of the present disclosure may not be utilized with server devices that are directly connected to primary I/O modules, and thus the information provided by the server device 208 a to the primary I/O module 204 a may not be utilized during the method 700.

Similarly as discussed above, the server device 208 b may transmit a discovery communication via its communication system 508 and via the secondary I/O module 206 a to the primary I/O module engine 304 in the primary I/O module 204 a/300 via the downlink port 816 a in the examples below, with that discovery communication identifying itself, the rack chassis identity of the rack chassis 806 in which the server device 208 b is located, a slot identity of the slot in the rack chassis 806 in which the server device 208 b is located, an I/O module identity and I/O module type of the secondary I/O module 204 b to which the server device 208 a is connected, a port identity of the port 808 on the server device 208 b that is connected to the secondary I/O module 206 a, and/or other information that would be apparent to one of skill in the art in possession of the present disclosure. In response to receiving the discovery communication from the server device 208 b via its downlink port 816 a, the primary I/O module engine 304 may use the information in that discovery communication to identify that the server device 208 b is connected to the downlink port 816 a on the primary I/O module 204 a via the secondary I/O module 206 a and, in response, provide that discovery communication to the fabric manager engine 604 in the fabric manager system 210/600. Furthermore, as will be appreciated by one of skill in the art in possession of the present disclosure, any primary I/O module in the port configuration migration system of the present disclosure may forward to the fabric manager system any discovery communications received from server devices that are connected to those primary I/O modules via a secondary I/O module.

In response to receiving the discovery communication from the primary I/O module 204 a, the fabric manger engine 604 in the fabric manager system 210/600 may use the information in that discovery communication to identify that the server device 208 b is connected to the downlink port 816 a on the primary I/O module 204 a via the secondary I/O module 206 a, and that the downlink port 816 a is part of a first port group in the primary I/O module 204 a that includes the downlink ports 816 a-816 h. As will be appreciated by one of skill in the art in possession of the present disclosure, the above discovery operations may be performed for any server devices in the port configuration migration system 200 in order to, for example, identify the server devices 208 b and 208 c that are connected to the primary I/O modules 204 a and 204 b via the secondary I/O modules 206 a and 206 b in FIG. 2 . However, while specific discovery operations have been described, one of skill in the art in possession of the present disclosure will appreciate that server devices connected to primary I/O modules via secondary I/O modules may be identified in a variety of manners that will fall within the scope of the present disclosure as well.

In an embodiment of block 702, the fabric manager engine 604 in the fabric manager system 600 may operate to inform a network administrator or other user of the secondary I/O modules that couple server devices to port groups in primary I/O modules. For example, with reference to FIG. 8A, at block 702 the fabric manager engine 604 in the fabric manager system 600 may inform a network administrator or other user of the secondary I/O module 206 a that couples the server device 208 b to the port 816 a in the first port group in the primary I/O module 204 a that includes the ports 816 a-816 h. Furthermore, at block 702, the fabric manager engine 604 in the fabric manager system 600 may then request that the network administrator or other user select a virtual slot identifier identifying a virtual slot for each identified secondary I/O module, and in response to receiving a virtual slot identifier, may assign that virtual slot identifier to that secondary I/O module. As such, at block 702, the secondary I/O module 206 a may be assigned a virtual slot identifier (e.g., virtual slot identifier “80” in the examples below). As will be appreciated by one of skill in the art in possession of the present disclosure, the assignment of virtual slot identifiers to secondary I/O modules may include associating a secondary I/O module identifier (e.g., a “service tag” or other unique identifier) with that virtual slot identifier in the fabric manager database 606, which allows the assignment of that virtual slot identifier to that secondary I/O module to remain persistent until the network administrator or other user removes or otherwise changes that assignment.

In an embodiment of block 702, the fabric manager engine 604 in the fabric manager system 600 may then generate a virtual interface for each downlink port in a port group on a primary I/O module that is connected to a secondary I/O module. For example, at block 702 the fabric manager engine 604 in the fabric manager system 600 may then generate a virtual interface for each downlink port 816 a-816 h in the first port group on the primary I/O module 204 a that is connected to the secondary I/O module 206 a (e.g., a virtual interface “1” for the downlink port 816 a in the first port group on the primary I/O module 204 a, a virtual interface “2” for the downlink port 816 b in the first port group on the primary I/O module 204 a, and up to a virtual interface “8” for the downlink port 816 h in the first port group on the primary I/O module 204 a.) However, while a specific technique for generating virtual interface for downlink ports in a port group on a primary I/O module that is connected to a secondary I/O module has been described, one of skill in the art in possession of the present disclosure will recognize that the virtual interfaces discussed above may be generated in a variety of manners that will fall within the scope of the present disclosure as well.

The method 700 then proceeds to block 704 where the fabric manger system maps the virtual interface to a first primary I/O module downlink port on a primary I/O module that is connected to a first secondary I/O module uplink port on a secondary I/O module that is connected to a server device. In an embodiment, at block 704, the fabric manager engine 604 in the fabric manager system 600 may operate to map the virtual interfaces generated at block 702 to the downlink ports on the primary I/O module that are connected to secondary I/O module uplink ports on the secondary I/O module that is connected to the server device. For example, with reference to FIG. 8A, at block 704, the fabric manager engine 604 in the fabric manager system 600 may operate to map the virtual interface “1” generated for the downlink port 816 a on the primary I/O module 204 a to that downlink port 816 a that is connected to the uplink port 814 a on the secondary I/O module 206 a, with that secondary I/O module 206 a connected to the server device 208 b.

In one specific example, the mapping of the virtual interface to the downlink port 816 a on the primary I/O module 204 a may identify the virtual interface (e.g., “1”), the virtual slot identifier for the virtual slot assigned to the secondary I/O module 206 a (e.g., “80”), and the uplink port 814 a (e.g., “1”) on the secondary I/O module 206 a that is connected to the downlink port 816 a on the primary I/O module 204 a, which provides a virtual interface “1/80/1” that provides a virtual direct connection to the server device 208 b such that the server device 208 b appears to be directly connected to that virtual interface “1/80/1” from the point of view of a user viewing connections to the primary I/O module 204 a (i.e., rather than via the secondary I/O module 206 a.) As such, one of skill in the art in possession of the present disclosure will appreciate that a network administrator or other user of the primary I/O module may use a Command Link Interface (CLI) to view the direct connection of the server device 208 a to the downlink port 804 on the primary I/O module 204 a, as well as to view the virtual direct connection of the server device 208 b to the virtual interface “1/80/1” provided for the primary I/O module 204 a.

Similarly, a virtual interface “2/80/2” may be mapped to the downlink port 816 b in the first port group on the primary I/O module 204 a that is connected to the uplink port 814 b on the secondary I/O module 206 a, a virtual interface “3/80/3” may be mapped to the downlink port 816 c in the first port group on the primary I/O module 204 a that is connected to the uplink port 814 c on the secondary I/O module 206 a, and up to a virtual interface “8/80/8” may be mapped to the downlink port 816 h in the first port group on the primary I/O module 204 a that is connected to the uplink port 814 h on the secondary I/O module 206 a. However, while a specific example of virtual interface/primary I/O module downlink port mapping has been described, one of skill in the art in possession of the present disclosure will appreciate that the virtual interfaces of the present disclosure may be mapped to physical downlink ports on the primary I/O module that are connected to secondary I/O modules in a variety of manners that will fall within the scope of the present disclosure as well.

The method 700 then proceeds to block 706 where the fabric manger system configures the virtual interface with server device communication information. In an embodiment, at block 706, the fabric manager engine 604 in the fabric manager system 600 may request the network administrator or other user to provide server device communication information for each of the virtual interfaces that are coupled via the secondary I/O modules to server devices. For example, at block 706 the fabric manager engine 604 in the fabric manager system 600 may request the network administrator or other user to provide server device communication information for the virtual interface “1/80/1” that provides the virtual direct connection to the server device 208 b. As will be appreciate by one of skill in the art in possession of the present disclosure, the server device 208 b may utilize a Virtual Local Area Network (VLAN), Internet Protocol (IP) information, and/or other information for communications via the primary I/O module 204 a and, as such, may require VLAN configuration information for that VLAN, IP configuration information, and/or other information to be used to configure ports through which those communications will be transmitted. As such, at block 706 the fabric manager engine 604 in the fabric manager system 600 may request the network administrator or other user to provide that VLAN configuration information, IP information, and/or other information for the virtual interface “1/80/1” that provides the virtual direct connection to the server device 208 b and, upon receiving that VLAN configuration information, IP information, and/or other information, may configure the virtual interface “1/80/1” with that VLAN configuration information, IP information, and/or other information. However, while specific server device communication information has been described, one of skill in the art in possession of the present disclosure will appreciate that any of a variety of server device communication information that allows for the transmission of communications from a server device may be utilized to configure the virtual interfaces at block 706 while remaining within the scope of the present disclosure as well.

As will be appreciated by one of skill in the art in possession of the present disclosure, following the mapping of the virtual interfaces to the downlink ports on a primary I/O module to provide respective virtual direct connections to respective server devices, and then the configuration of those virtual interfaces with server device communication information for those server devices, the primary I/O modules may transmit communications received from those servers devices using those virtual interfaces that were configured with the server device communication information. For example, the primary I/O module engine 304 in the primary I/O module 204 a/300 may receive communications generated by the server device 208 b and transmitted via the secondary I/O module 206 a (e.g., through the downlink port 816 a on the primary I/O module 204 a/300 from the uplink port 814 a on the secondary I/O module 206 a) and, due to the mapping of the virtual interface “1/80/1” to the downlink port 816 a on the primary I/O module 204 a/300, will operate to transmit those communications using virtual interface “1/80/1” that was configured with the server device communication information for the server device 208 b (e.g., VLAN information for the VLAN that the server device 208 b is configure to use, IP information used by the server device 208 b, etc.). As such, as long as the coupling between the primary I/O module and secondary I/O module of the present disclosure remains (e.g., the coupling 812 between the primary I/O module 204 a and the secondary I/O module 206 a), one of skill in the art in possession of the present disclosure will appreciate that the primary I/O module may transmit communications received from any server device connected to the primary I/O module via the secondary I/O module using the virtual interface that was configured with the server device communication information for that server device and that was mapped to the downlink port on the primary I/O module through which those communications will be received.

The method 700 then proceeds to block 708 where the fabric manger system receives discovery communications from the server device via a second primary I/O module downlink port on the primary I/O module that is connected to a second secondary I/O module uplink port on the secondary I/O module. In an embodiment, at block 708, the coupling between a primary I/O module and a secondary I/O module may change. For example, as illustrated in FIG. 8B, the coupling 812 may be disconnected from the first port group on the primary I/O module 204 a that includes downlink ports 816 a-816 h, and may be reconnected to a second port group on the primary I/O module 204 a that includes downlink ports 818 a-818 h. As will be appreciated by one of skill in the art in possession of the present disclosure, a network administrator or other user may change a cabled connection (e.g., the coupling 812) of a secondary I/O module to a primary I/O module for any of a variety of reasons, and thus the disconnection of the coupling 812 from the first port group on the primary I/O module 204 a that includes downlink ports 816 a-816 h and its reconnection to a second port group on the primary I/O module 204 a that includes the downlink ports 818 a-818 h may be performed for any of those reasons while remaining within the scope of the present disclosure as well. However, while the secondary I/O module is illustrated as being coupled to different port groups on the same primary I/O module, one of skill in the art in possession of the present disclosure will appreciate that the teachings of the present disclosure allow a secondary I/O module to be disconnected from a first primary I/O module (e.g., the primary I/O module 204 a) and connected to a second primary I/O module (e.g., the primary I/O module 204 b) while providing the port configuration migration functionality of the present disclosure as well.

In one specific example, following the connection of the coupling 812 to the second port group on the primary I/O module 204 a that includes downlink ports 818 a-818, the fabric manager engine 604 in the fabric manager system 210/600 may operate to perform the discovery operations discussed above and described in U.S. patent application Ser. No. 16/526,624, filed on Jul. 30, 2019, the disclosure of which is incorporated herein by reference. As such, similarly as discussed above, following the connection of the coupling 812 to the second port group on the primary I/O module 204 a that includes downlink ports 818 a-818, the server device 208 b may communicate with an enclosure controller in the rack chassis 210 b and, in response, provide discovery communications (e.g., via LLDP communications) via the downlink port 818 a on the primary I/O module 204 a that may identify itself, the rack chassis identity of the rack chassis 806 in which the server device 208 b is located, a slot identity of the slot in the rack chassis 806 in which the server device 208 b is located, an I/O module identity and I/O module type of the secondary I/O module 204 b to which the server device 208 a is connected, a port identity of the port 808 on the server device 208 b that is connected to the secondary I/O module 206 a, and/or other information that would be apparent to one of skill in the art in possession of the present disclosure. In response to receiving the discovery communication via its downlink port 818 a, the primary I/O module engine 304 in the primary I/O module 204 a/300 will recognize that the server device 208 b is connected to the primary I/O module 204 a via the secondary I/O module 206 a and, in response, forward those discovery communications to the fabric manger system 210/600.

The method 700 then proceeds to block 710 where the fabric manger system remaps the virtual interface to the second primary I/O module downlink port on the primary I/O module that is connected to the second secondary I/O module uplink port on the secondary I/O module. In an embodiment, at block 710 and in response to receiving the discovery communication, the fabric manager engine 604 in the fabric manager system 210/600 may identify that the server device 208 b is coupled to the downlink port 818 a on the primary I/O module 204 a via the secondary I/O module 206 a. The fabric manager engine 604 in the fabric manager system 210/600 may then determine that the virtual interface “1/80/1” provides a virtual direct connection for the server device 208 b to the downlink port 816 a on the primary I/O module 204 a that was previously connected to the secondary I/O module 206 a via its first port group that includes the downlink ports 816 a-816 h, and that the receiving of the discovery communication from the server device 208 b via the downlink port 818 a indicates that the secondary I/O module 206 a is now connected to the second port group on the primary I/O module 204 a that includes the downlink ports 818 a-818 h.

In response to determining that the connection between the primary I/O module 204 a and the secondary I/O module 206 a has changed, the fabric manager engine 604 in the fabric manager system 210/600 may operate to remap the virtual interfaces “1/80/1”, “2/80/2”, and up to “8/80/8” (which were previously mapped to the downlink ports 816 a, 816 b, and up to 816 h, respectively, on the primary I/O module 204 a) to the downlink ports 818 a, 818 b, and up to 818 h, respectively, on the primary I/O module 204 a. As will be appreciated by one of skill in the art in possession of the present disclosure, the remapping of the virtual interfaces “1/80/1”, “2/80/2”, and up to “8/80/8” to the downlink ports 818 a, 818 b, and up to 818 h, respectively, on the primary I/O module 204 a retains the configuration of those virtual interfaces “1/80/1”, “2/80/2”, and up to “8/80/8” that was performed using the server device communication information (e.g., VLAN information, IP information, etc.). As such, the remapping of the virtual interface “1/80/1” from the downlink port 816 a to the downlink port 818 a on the primary I/O module 204 a will allow communications received from the server device 208 b via the downlink port 818 a that is mapped to the virtual interface “1/80/1” to be transmitted using the configuration that was previously applied to that virtual interface “1/80/1”.

As will be appreciated by one of skill in the art in possession of the present disclosure, following the remapping of the virtual interfaces to new downlink ports on a primary I/O module, the primary I/O modules may transmit communications received from those server devices using the virtual interfaces configured with the server device communication information. For example, the primary I/O module engine 304 in the primary I/O module 204 a/300 may receive communications generated by the server device 208 b and transmitted via the secondary I/O module 206 a (i.e., to the downlink port 818 a on the primary I/O module 204 a/300 from the uplink port 814 a on the secondary I/O module 206 a) and, due to the remapping of the virtual interface “1/80/1” to the downlink port 818 a on the primary I/O module 204 a/300, will operate to transmit those communications using virtual interface “1/80/1” that was configured with the server device communication information for the server device 208 b (e.g., VLAN information for the VLAN that the server device 208 b is configure to use, IP information for the server device 208 b, etc.). As such, when the coupling between the primary I/O module and secondary I/O module of the present disclosure changes (e.g., the coupling 812 is moved between port groups on the primary I/O module 204 a), the virtual interfaces may be remapped from the previously connected downlink ports on the primary I/O module to the newly connected downlink ports on the primary I/O module such that the primary I/O module may transmit communications received from any server device connected to the primary I/O module via the secondary I/O module using the virtual interface that was configured using the server device communication information for that server device and remapped to the newly connected downlink ports upon which those communications are received. As discussed above, while the virtual interfaces are described as being remapped between downlink ports on the same primary I/O module, one of skill in the art in possession of the present disclosure will recognize that the virtual interfaces of the present disclosure may be remapped between downlink ports on different primary I/O modules while remaining within the scope of the present disclosure as well.

Thus, systems and methods have been described that provide for the automatic migration of port configurations when connections between a secondary I/O module and a primary I/O module change. For example, a secondary I/O module may include a secondary I/O module downlink port that is connected to the server device, as well as first and second secondary I/O module uplink ports that are connected to respective first and second primary I/O module downlink ports on a primary I/O module. A fabric manager system that is coupled to the primary I/O module may operate to map a virtual interface to the first primary I/O module downlink port on the primary I/O module, with the virtual interface providing a virtual direct connection of the virtual interface to the server device, and may then configure the virtual interface with server device communication configuration information for the server device such that data communications received via the first primary I/O module downlink port are transmitted using the virtual interface configured with the server device communication configuration information for the server device. When the fabric manager system receives a discovery communication from the server device via the second primary I/O module downlink port on the primary I/O module due to a connection change between the secondary I/O module and the primary I/O module, it remaps the virtual interface to the second primary I/O module downlink port such that data communications received via the second primary I/O module downlink port are transmitted using the virtual interface configured with the server device communication configuration information for the server device. As such, the manual reconfiguration of primary I/O modules in response to connection changes between those primary I/O modules and secondary I/O modules is eliminated, thus eliminating the system downtime associated with such reconfigurations.
